To be honest, I was disappointed with this drama. I love Kim Soo Hyun and the female lead (Jeon Ji Hyun?) is actually a good actress too but the plot didn't do it for me and the story moved on at a laggy pace in my opinion. Especially the ending was disappointing. I think they could've done a lot better with it. The saving grace of this drama for me was Kim Soo Hyun.
